A disturbing tally of the heat records that broke in 2019

Signals Summary: Global Warming is amplifying the intensity, duration and frequency of extreme heat and heat waves, and July 2019 was the hottest month ever on record. 

Article Excerpt: For example, so far this year (as of Dec. 16) there have been 42,487 daily high temperature records set around the world, versus 25,027 low records. Meanwhile, 364 all-time high temperatures were set in 2019, versus just 70 all-time lows. This makes sense.

As the planet warms, the ocean's total heat content increases. This heating trend, expectedly, continued in 2019. Warmer oceans also mean ever-hotter marine heat waves.
